The RC4 stream cipher is the most widely used software based stream cipher. It is based on a secret internal state of N = 256 bytes and two pointers. This paper proposes an efficie...
DECIM is a hardware oriented stream cipher with an 80-bit key and a 64-bit IV. In this paper, we point out two serious flaws in DECIM. One flaw is in the initialization of DECIM. I...
The self-shrinking generator was introduced in 1994. It is based on the idea behind the shrinking generator and despite its simplicity it has remained remarkably resistant to effic...
In this paper we revisit a known but ignored weakness of the RC4 keystream generator, where secret state info leaks to the generated keystream, and show that this leakage, also kno...
